a friend of mine is planning to marry a Turkish man and live in turkey, she is not Turkish, he was married and now the divorce case is in court (still no decision has been made by the judge) he told her he would marry her in the religious court (they are both muslim) and he will marry her in a civil way when his divorce is final.

is this legal? will she have any rights as a wife? what about if they have children, will they be legitimate? how long do divorce procedures take until they are final?
